APMdisc: An online computer program for the geochemical discrimination ofsiliciclastic sediments from active and passive margins
An online computer program called APMdisc (Active and Passive Margin discrimination) for the discrimination of siliciclastic sediments from active and passive margin settings was written in Java along with the ZK framework. APMdisc calculates four complex discriminant functions (DFilr(A-P)M and DFml...
